The border between 2 boroughs

The course of the Petuel Tunnel marks the border between the Boroughs of Milbertshofen-Am Hart and Schwabing-West. The tunnel which was built by using the cut-and-cover method consists of 2 tubes with a length of approximately 1,472 m, each with 2 to 3 lanes of one-way traffic. An approximately 235 m long glass enclosure connects with the tunnel at the East Portal exit. Besides the main portals there are additional entrance and exit ramps, which lead as about 265 m long side directly to the motorway A9.

Complex ventilation and traffic control

A fire inside the tunnel is a horror scenario and the ventilation and traffic control system has to fulfil high requirements. Besides a fast localisation and detection of the fire, complex programmes are of paramount importance for the regulation of the traffic and the tunnel ventilation. In case of a disaster these programmes automatically introduce actions that are of vital importance for the safety of the drivers.
